Bug Description

Binary package hint: ffmpeg

When I convert .flv video with nellymoser audio codec, ffmpeg Incorrectly determine the sampling rate. I get the video with the slow sound. I try to compile ffmpeg from source(with apt-get source), but it did not help.Sorry for my bad english.

I don't totally understand what problem(s) you are experiencing. In Karmic your command caused FFmpeg to crash, but the otutput file is still created (FFmpeg output attached to this comment). The crash seems to be caused by the -async 1 option. The output file however plays at a lower pitch than the original when I use ffplay. Which of these issues apply to you?

When I convert video with my parameters ffmpeg didnt crash, but output file plays at a lower pitch, When I convert without -async 1, output file plays at a lower pitch and sound desynchronizes with video.
